Building first computer, I get fast, high beeping/whining when I try to turn on

[rifem]

I'm building my first computer and when I try to turn it on I get no signal to my monitor and a high whining noise, possibly a very fast beeping. At first I thought that maybe I had a bad PSU, but now I'm wondering if it is an error noise of some sort. Any ideas?

Specs:
EVGA GeForce 9800 GT
Rosewill RP600V2-S-SL 600W
Seagate Barracuda 500GB 7200 RPM 32MB
GIGABYTE GA-EP45-UD3P
Intel Core 2 Duo E8600 3.33GHz
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 800 (PC2 6400)

Are you sure your motherboard and your CPU are match? or maybe your BIOS setting is wrong or not match to your hardware, your explain isn't complete!

Hi

I know that these are simple checks and you might have already done them but there is no harm in starting at the beginning with the simple things!

Check that your graphics card is seated properly in the right slot and that your connections between the monitor and graphics card are good. 

Any bent pins in the cable or graphics card?

Is your monitor configured correctly.  For instance, I get a no signal report when HDMI is selected and I am running from VGA! 

Good luck

Lol, I finally figured it out. I forgot to plug a power chord from my PSU straight into my video card. I know, dumb mistake. Thanks for your ideas though guys
